| Summary: | © 2016 Trans Tech Publications, Switzerland. Ba(Fe 0.8 Ga 0.2 ) 0.5 Nb 0.5 O 3 ceramics were synthesized via a solid state reaction method. The Raman spectrum analysis indicated that the sample presented a cubic structure. Dielectric measurement on the ceramics with Ag-paste and Au-sputtered electrodes showed that all ceramic samples exhibited very high dielectric constants with a strong frequency dispersion. The Ausputtered electrode samples presented higher dielectric tunability the dielectric constant than Agpaste electrode samples.This behaviour was related with the electrode effect, occured in the studied samples. |
